摘要:In recent years, the hypervelocity-impact (HVI) risk from meteoroid/orbital debris (M/OD) has become a growing threat to spacecrafts. To realize automatical M/OD risk assessments, it is necessary to evaluate the HVI damages by employing some effective nondestructive testing technologies. This topic introduces a damage evaluation method with multi-objective feature extraction optimization scheme in the thermal wave image technique, to quantificationally evaluate the M/OD HVI damages. The proposed MO-FEO method not only investigates the difference among temperature points in different thermal temperature categories, but also considers the correlation among temperature points of each thermal temperature category, to select the representative temperature point accurately. The multi-objective feature extraction is applied to search for the representative temperature points of the infrared thermal image sequence, the damage evaluation method contains variable step search and classification of temperature points, in order to enhance the detection efficiency. Experimental results including M/OD HVI tests are provided to demonstrate the capabilities of the proposed method.
